Reconstruction of money supply over the long run: the case of England, 1270–1870

I provide a time-series series for coin and money supply estimates for six hundred years of English history. I propose two main estimation methods. The first (the direct method), is used to measure the value of government-provided, legal-tender coin supply only. I propose two varieties of the direct method. Additionally, I propose an indirect method which relies on a combination of information about nominal GDP with an assumption regarding the evolution
of velocity in time, and which can be used to calculate coin supply and M2. Both methods rely on benchmark values known for certain years, but no particular benchmark is determinant for the results. The new methodologies which I set out here may serve as a blueprint for a similar reconstruction of coin and money supply series for other economies for which analogous data is available.
